Thanks! here are the pictures of both fish, Sol has a red outline where the cotton wool is, and Precioso is the purple red betta, and he just ate like 4 pellets today so I am really excited!! I did change his water again today and no more antibiotic since today was day 5 but as I mentioned before his fins are still falling, but he looks happy, is eating now and swims great! his tamp is between 72-75 degrees today.
Sol is also in around 72-75 degree water, does not eat anymore as he did yesterday and lays down on the bottom of his bowl, and also has random attacks where he splashes around like crazy and then lays down again. i also started Sol on the same antibiotic that Precioso was on, and aquarium salt, I add about 1/2 teaspoon to their water with every change and water conditioner.
